Out of all of the characters in the tv show or movie I name, who would you want to:

A) sleep with once
B) have a long term relationship with
Feel free to explain why.

First show: Firefly or the movie Serenity

Personally:
A) Enora, because duh
B) Kaylee, because River's nuts and I follow the idea "don't stick your sick in crazy.  (And before you say "but she's 17",  Summer Glau was in her low 20s when she played River.)
